nonviscous
  ناوشکسان   
nâvošksân

Fr.: non visqueux   

Fluid mechanics: Having no → viscosity. Same as → inviscid.

From → non- + → viscous.

viscous
  وشکسان   
vošksân (#)

Fr.: visqueux   

Having the property of → viscosity. See also: → viscous dissipation, → viscous fluid, → viscous force, → nonviscous.

M.E., from M.Fr. viscous, from L. viscosus "sticky," from viscum "anything sticky; mistletoe."

From vošk "a kind of sticky gum" + -sân suffix of similarity, from sân "way, manner."

viscous dissipation
  افتال ِ وشکسان   
eftâl-e vošksân

Fr.: dissipation visqueuse   

A degradation of → mechanical energy that is irreversibly converted to → thermal energy due to → viscous forces in the → fluid. Viscous dissipation occurs in → turbulent flows.

viscous; → dissipation.

viscous fluid
  شاره‌ی ِ وشکسان   
šârre-ye vošksân (#)

Fr.: fluide visqueux   

A fluid whose viscosity is sufficiently large to make the viscous forces a significant part of the total force field in the fluid.

viscous; → fluid.

viscous force
  نیروی ِ وشکسان   
niru-ye vošksân

Fr.: force visqueuse   

The force per unit volume or per unit mass arising from the action of tangential stresses in a moving → viscous fluid.

viscous; → force.
